Des Moines police are investigating three shootings that took place in a 24 hour span.

On Saturday night, a 22-year-old was shot in the thigh at 17th and Clark streets.

On Sunday morning, a south side robbery ended with a man being shot in his leg.

On Sunday afternoon, another shooting happened at 13th and College streets. The shooter got away before police arrived.

"A lot of these things can be solved and, or stopped by people active in the community," said Sgt. Jason Halifax with Des Moines police.

People like Calvetta Williams said she has made it her mission to put an end to the violence and weekends like this only inspire her.

"It makes me want to fight harder. It makes me want to talk more. We can't discouraged because this happened. We just need to be thankful no one lost their life," Williams said.

Two weeks ago, dozens of young people met with Williams to join the cause. They signed what became known as a peace treaty. But Williams said that term in incorrect because those who signed were all on the same side. Now she's reaching out to everyone else.

"Just step up. Come talk to Mothers Against Violence. Just because we sat down and talked to that group, we're still open to talking to everyone else. We care about all of them," Williams said.

Even those behind the latest shootings.

"Don't get discouraged. And the ones who are doing the shooting, there is still hope for you. You didn't kill anybody, you're not going to go to jail. No one's life has been lost," Williams said.

Police said they can't quantify the effect from groups like Mothers Against Violence, but they believe they do help to reduce crime in the community.
